All of our Aluminum knife frames are precision machined from the same 6061-T6511 Aluminum material as with our Aluminum handgun grips. All of our G10, G-Mascus frames and scales are precision machined from the same G10 material as with our G10 handgun grips. When the ammo runs dry, it’s better to have it and not need it, then need it and not have it…that, of course is one of our exclusive ZX-F01 Zombie-X Fixed Blade Knives. Forged from the same EX-F01 stock, only Zombiefied with Zombie-X Green Pearlized Polymer scales and “ZOMBIE-X” laser engraved on the blade.
